Criminal justice reform advocates say a new directive for federal prosecutors to charge suspects with the most serious provable offense would target Black and brown bodies.

Making good on the Trump administration’s pledge to promote a Blue Lives Matter agenda, Attorney General Jeff Sessions on Friday issued a new directive for federal prosecutors to “charge suspects with the most serious offense you can prove,” reports CNN.

Sessions outlined the order in a brief one-page memo, which represents a dramatic departure from Obama-era criminal justice reform measures. “The most serious offenses are those that carry the most substantial guidelines sentence, including mandatory minimum sentences,” Sessions states in the memo.

The announcement was criticized on Twitter by the Advancement Project, a nonprofit group that focuses on racial justice issues, which called it an attack on people of color.

Other Twitter users also slammed the directive, highlighting the nation’s racist history of using prisons to oppress Black and brown bodies.

Other users noted that the directive could work in favor of federal investigators currently engaged in probing the Trump campaign’s alleged involvement in Russiagate.
